Application filed September22f 1916. Serial No. 1213658 To all whom z'tmay concern:

Be it known that I, OsoA-RC. BnnNAnma citizen ofthe Uni-ted States, residing at-El P aso, in-the county of El Paso and State of Texas, have invented new and usefullnn provements in Projecting-Mach111es,'of -W-l110l1 the following is a specification.

This invention relates-to advertising machines or devices the objectin view beingto simplify and improve the constructlon set forth in my prior Patent No. 1,069,521dated Aug-est 5, 1913, to the end that the mechanism involved 7 will be 1 productive of greater accuracy and reliability thus insuring the proper Working of the entire mechanism and reducing to a minimum the liabillty'of any part of the mechanism getting out of order,

Another object in view is to adapt amachine of'the-class referred to to be used in such cards, surfaces or matter during the day time or after dark.

Another important object of'the inven tion isto provide in connection with a rev oluble magazine contain ng slides adapted to be progected therefrom, and a display receiver associated therewith, driving mech-' anism for actuatmg said magaz ne With an intermittent movement, and novel means-for causing said mechanism to operate contin-" uously without any attentlon 011 thepart-of' the operator, or tobe controlled by an-operator sothat the periodsef-restor dwell:

between the exhibition of the slides, may

be varied at the Willof-the operatonthus adapting the machine partlcularly for lecture purposes, the operation of the-machine being controlled at any desired distance therefrom by thev lecturer.

lVith the above and other objects ii -view,

the invention consists inthe novel construction, combinatlon and arrangement ofrparts,

Fig. 15 is a fragmentary vertical section showing the magazine" locking means Fig. 16 is a fragmentary vertical section V of the slide-displayingreceiver, Referring to the drawings A designates generallya frame, certain parts Willbe here nates the base ofthe frame and 2 a,pair of oppositely arranged uprightswhich' support the-shaft?) of a revolub-lema gazine designated generallyat B' and adapted-to carry a circular series of radially movable slides C the majorportion of each, ofwhich is adapted to be projectedbeyondthe periphery of the magazineinto a receiver designated gene erally at D Where said slides'areldisplayed in a manner hereinafter more particularly referred-to;

The magazine comprises two diskshaped heads 4 arranged in spaced relation to; each other-and mounted upon the'shaft 3, the said plates"beingformed-with radial guide Ways 5 arranged intransversely alined pairs to portions of the heads 4 separated by the guide ways 5. Tie-bolts 8 connect theheads 4-and the annular bands 6 at intervals. The bands 6 are formed in their outer peripheries and in line with the guide ways 5, with notches 9 forming shoulders which are successively engaged by a feed dog 10 best shown in Fig. 6, said dog having a lip 11 to enter the notches 9 and the dog being pressed toward its engaging position by means of a spring 12which rests at its free extremity against'theperiphery of one of the 1naga Qzine heads and the adjacent band 6. The

feed dog l Oisrcarried by a pivot 13 on a feed dog carrier 14 shown in the form of an arm which is journaled at one end on the shaft3 and provided beyond the pivot 13' with aprojecting portion 15 having a dwell face 16 the function of which will-appear.

In order to prevent the slides or holders from dropping out of their guide ways in the magazine at the lower part of the latter,

I provide a guard or track rail 17 one end of which is connected by a fastener 18 to a cross bar 19 which is terminally fastened at 20 to arcuate extensions21 of the frame of the machine. The other end of the rail 17 is fastened at 22' to another cross bar 23 terminally fastened to vertical bars 24 of the frame, the frame members 24 being connected by arcuate frame pieces 25 to upright frame p eces 26 and .also,to the base 1, the frame pieces 25, serving as supports for the shaft 27 of the driving mechanism hereinafter more particularly described.

. The driving mechanism for impartingmoe tion to the magazine, is shown; as comprising" a motor 28 which drivesthrough ajbelt 29 a worm shaft 30. the worm 31 of which drive'sja' worm wheel 32 on a shaft33 supported by the arcuate frame pieces 25. A pinion 34 on the shaft 33 drives a large wheel 35 which constitutes the master gear or wheel of the driving mechanism. The wheel 35 is provid ed uponv one side thereof withja projection 36 shown in theform of av pin or stud which at a oertainnoint in the travel of the wheel 4 comes incontact with thecurvediend portion. of a slide operating lever37 fulcrumed at 38011 one of the framepieces 24above decarrying 'at its extremity a projection36 which performs thesame function, asthe' projection. 36. 'ust referred to, said projection 36 cooperating with another lever 37 at the opposite side'of" the machine frame and corresponding in all respectlwith the These" bands or hoops'serve torigidly connect the first named lever 37 The'levers 37 are connected bypivotal links 40 to slide controlling levers 41 which are fulcrumed between thelr. endson journals 42 on the uprights 2 of the frame. The levers 41 are also connected by pivotal links 43 to a pair of slide projecting members 44 shown in the form of levers pivotally supported at 45 on the 'arcu ate extensions 21 of the frame.

By now referring to Figs. 10 and 11 in connectionwith Fig. 1 it will be seen that each of the-slide projectingmembers 44 is formed with a rounded end portion 45 which slides through a guide way 46 in a vertically movable runner 47 This runner serves as a vertically movable support for the slides,

V 11, the endportions 45 thereof slide through the guide ways 46 of the runners while moving said runners in an upwarddirection and thereby elevating or projecting one of the slides or holders from the magazine into the display receiver above. This upward movement of the projecting members 44 is caused bythe projections 36. and 36 coming in contact with the levels 41 which areformed with notches bounded by inclined curvilinear faces 51 and 52 against which said projections on the wheel 35 ride while said wheel continues to turn. As the projections 36 and 36j depress the ends of the levers 41 adjacent to the wheel 35; the opposite ends of said levers, through'the medium 7 of the links 43 swing the slide projecting members upwardly. The parts referred to remain in this position until the wheel 35 has made about three-fourths of a revolue tion when the projections 36 and 361 come in contact with the levers 37 and rock said,

swung upwardly and by'means of the links 43, the slide projecting members 44 are swung do nwardly. Thispermitsthe runnersto- I I travel in a downward direction and lower the slide supported thereby. into its guide ways 5 in'the magazine, In theftravel of 1 tact with and depresses the adjacent end of the feed 'dogcarrier 14 thereby causing the dog; 10 to turn the magazine adistance equal succeeding slide into position to 'beprojected' I V the projection36,'the latter comes intocon-T scribed. I Fast-on theshaft 27. 1S an arm' 39 upwardly into thereceiyer. .The dwell face 16' of the feed de carri erlenablesthe e '10;

to be held at the lower limit of its movement a suflicient lengthjof time to allow the slide projecting members 44 to reach the upper limit of their movement and fully project a slide. As soolr asthe projectionf36 passes beyond'the extremityjof the dwell face 16, a spring 53 acting on the feed dog carrier 14 serves to return thefeed dog liO to the next succeeding notch 9 of the magazine. This provides for the intermittentmovement imparted to the magazine.

The levers 41 are shown as provided with arcuate dwell faces 54 concentric with the axis of the shaft 27 against which the projections 36 and 36 ride after thefeed dog carrier 14 is released andcarried upwardly by the action of the spring 53. In this way the levers 41 are held 'in t h eposition illustrated in Figs. 1 and 2. This serves toprevent the. slide projecting members 44 from movingdownwardly to any extent. As an additional safe-guard, I employ in connection with the magazine, locking mechanism for holding the magazine stationary when.

each slide or holder is in line with the rece ver. The lock 1s shown 'ln the form of a vertically movable slldlllg member 5 5 having a shoulder 56 against which the ad-j jacent lever 41 is adapted to strike in the downward movement of that arm of the lever to which the link 43 is connected. The

member is provided at its lower end with an inwardly extending lip 57 which isnor mally held in engagement with one of the guide ways 5 of the magazine by means of an underlying spring 58 thereby preventing any possibility of the magazine turning at an inopportune moment. 7 projecting members 44approach the lower limit of movement and the slide. or holder has moved downwardly. into itsnormal position in the magazine, the'lever 41 acting against the shoulder 56 throwstheilocking lip 57 out of engagement with. the magazine,

leaving thexsame free to be actedupon by the .feed' dog 10 for the purpose above described. 1

As an additional safeguard to prevent rotation of the magazine,'a spring detent 59 is fastened to the guardrail 17 and formed with an offsetfiO toengage a cross rod 61 terminally held by lugs 62 on the levers 41. When said levers rea'chthelower limit of their movement, the detent-59 snaps into engagement with thecross rod "61 thus holding thelever mechanism until the projections 36 and 36 again depress' the ladjacent ends of. the levers 37 for the purpose above set forth.

In order to provide for stopping themotor and therebyof course terminating for the time beingthe operation of the device as the whole I provide a motor switch '63" When the slide 1 operates the trip 81.

hich is tli eramm ia l .eharn .1 F 12 as comprising two 'yrldmg contacts 64 and (i5 and a shdable contact or bridge piece 66 having an ofi'rset orlugfiT adapted to engage in either one of apair of .depres-;

siej sfis and 6 9 in the contact .65, this being for thepurpose, of holding the sliding eontact. 6.61 either or out of engagement with the. contactifiiii, the object. ofcourse being to makeand break the, circuit. The switch member ,63. isshown as providedwith a head 70 which, as bestillustrated in. Fig. 9, is attached .to and actuated a. slidableswitch operating member .71 from, which extends a plunger rod 72 having a head 7 3 by means of which the Ime'mber. 71 may be pushed in: a, direction to..close. the circuit of theswitch .63 and thereby start the motor. The sliding member 71 is mounted in a suitable casing 7 4 together with: a pneumatic cylinder 75 in which ,operates a plunger 76, which is connected Qat 77 to. anarm 7 8 of the member '71. 'A flexible tube 79 equipped with a hand pressure bulb communicates with the cylinder 7.5- so that the .hereinabove described. After the motoris started in themanner described either by compressing the hand bulb 80o'r pressing inwardly on the head 73 the motor will operate continuously.

To provide for, cutting out the motor and interrupting the opeigation of tl1e machine,

a trip 81 ispivotally mounted at 82 on the sliding member? 1 and is formedwith alip or projection 83 against which another proj ect-ion, or pin-84 on the wheel 35 is adapted to-strike as indicated in Fig. 5. The trip 81 is pivotallymountedon themember 71v so that itmay turnto the tripping position shown in Fig. 5 or to anon tripping positioirasshown in Fig. 9. .Whenin a tripping position as shown in Fig. 5 in each revolution of the wheel 35, the pin or projection 84 will push against the lip 83 of the. trip and shift the sliding member 71- so as to break the circuit of the motor switch 63 by actuating the sliding contact 67 away fromthe cont-act64. When the motor started again, the wheel 35 again starts-to turn'in the same direction as beforefand keeps. turning until the projection 84 again After vthe circuit is broken the projection 84 overridesgthe trip 81 as the motor is overrun, The ,motoris start-ed again by actuating theslide 71 in the opposite direction, by finger pressure on 7 3 or by compressing bulb .80, .assistedby Y the spring'80 .Whichof itself is too weak to actuate theslide 21 to close;the.,circuit,'

on account of the resistance to said closing movement produced by the spring contact 87 (see Fig. 12). Y

In addition to the motor switch just hereinabove'describedI also employ a combined light and motor switch 85 which is diagrammatically shown in Fig. 12, being similar to the motor switch 63 in that it comprises the spring contacts 86 and 87, the sliding contact 88 and the ofi-set or lug 89 on the member 88 which engages one orthe other of depressions 89 and 90in the contact 87 'for making or breaking the circuit. The

sliding contact 88" is providedwith end portions 91 which are engaged by the arms 92 and 93'of 'a'plunger bar 94 having at one cally operating. the switch member 88 to cut' off the current from the motor a at a predetermined time. The wheel 98 is mounted in a suitable supporting casing 99 and "is provided on its periphery with ratchet teeth 100 engaged by a pawl 101 attached to a pawl carrier 102 which is journaled on the shaft 103 of the wheel 98. The adjacent band 6 of the magazine is formed at one point with a depression or notch '10-1 as shown in Fig. 1 to allow the pawl 101 to be retracted or thrown back by means of a spring 105, backward movement of the wheel 98'being prevented by a detent 106 mounted on the frame or casing 99. The shaft 103 has mounted on one endthereof .a pointer or indicator 107 which sweeps around a timing dial 108 suitably graduated to indicate periods of time such as. hours and fractions thereof as clearly indicated .inFig. 1. The indicator or pointer 107 may be set at any graduation on the dial 108 to provide for the continuous'run-' ning of the machine from any desired period f of time from afew.n1inutes to any number of hours. For such arrangement the trip 81 is shifted to the'position shown in 'Fig.

9 so that it will be. inoperative. The operation of the machinethen continues uninterruptedly until the pin or projection 97 act-' ing'against the face .96 and the plunger bar 94, breaks'the circuit'by moving the sliding contact 88 of the'combinedlight and motor; switch out ofengagement with the contact 86;

The wiring for the switches 63 and 85, the

' motor 28 and an illuminating lamp 109 is clearly sho-wninj Fig." 12"and may be del'.

One of the slides or slide holders is illus trated in detail in Fig. 13. Said slide or holder comprises a plate like body 130 having a central opening or orifice 131 and flanges 132 and 133 extending along parallel marginal edges thereof to receive guide and hold cards lantern slides and the like. The flange 132 is bent so as to form a shallow member 134 closed at one end by means of a stop or end wall 135 and open at the other end to receive a card for example. The flange 132 is also formed with a deeper portion 136 of less lengththan the member 134 and terminating in a closed end or stop shoulder 137, the deeper and shorter portion 136 of the flange being designed to receive a thicker glass or transparent lantern slide. Adjacent to the receiving end, the flange 132 is cut away at 138 to receive a bowed friction clasp 139 shown in the form of a spring having one end attached at 140 to said flange. The bowed portion of the clasp is so positioned that it will frictionally engage and hold either a card or a lantern slide. The extreme edges or margins 141 of the slide or holder C are slidingly received in the guide ways 5 of the heads of the maga zine as hereinaloove noted. 142 represents an auxiliary handle or knob on the plunger bar 94 for the convenience of the operator 1n stopping and starting the motor and turning on or ofl? the lamp 109.

The slide or holder which is movable up and down in the receiver only and which is controlled in its movements by the successive magazine slides or holders, is provided with flanges 132 and 133 on both faces thereof, said flanges being identical with those above described" in connection with the magazine slides or holders. By providing two sets of flanges as stated, the cards or slides may be inserted under the flanges and thereby arranged at either side of said additional or double slide as. shown in Fig. '16.
